Surface characterization of dinitrophenyl-diaminophenyl nanoplatform on glassy carbon

Ali Osman SOLAK

2,4-dinitrophenol (DNP) was covalently bonded to glassy carbon substrate by cyclic voltammetry (CV) technique. 2, 4-diaminophenol film (DAPO) was acquired with electrochemical reduction of 2,4-dinitrophenol film (DNPO). Prepared films were characterized by X-ray photoelectron spectroscopy (XPS) and germanium attenuated total reflection infrared (GATR-FT-IR) spectroscopy. A hemispherical germanium ATR element used with p-polarized light at 65° incidence angle yielded high signal/noise IR spectra for monolayer coverage of molecules on glassy carbon substrate. Layer thickness of films was measure ...Более

1,10-Phenanthroline modified glassy carbon electrode for voltammetric determination of cadmium(II) ions

Ali Osman SOLAK

This study reports the electrochemical modification of glassy carbon (GC) electrode surface with the electro-polymerized form of 1,10-phenanthroline monohydrate (PMH), the characterization of this polyphenanthroline modified electrode (PPMH/GC) and the electroanalytical application suitable for the determination of Cd(II) ions. The PPMH/GC electrode was characterized by cyclic voltammetry, chronoamperometry and atomic force microscopy and formation of polyphenanthroline layer grafted to surface of GC electrode was evidenced. Selectivity of PPMH/GC electrode towards heavy metal ions was investi ...Более

Preparation of molecularly imprinted PDMS elastomer for selective detection of folic acid in orange juice

Nahit AKTAŞ

Herein, it is reported an effective method to prepare novel molecularly imprinted polymers (MIP) on poly(dimethylsiloxane) (PDMS) elastomer via a combination of non-covalent imprinting approach and surface initiated reversible addition fragmentation chain transfer (SI-RAFT) polymerization for sensitive and selective detection of folic acid (FA). For this purpose, 2-(2-Methoxyethoxy) ethyl methacrylate (MEOMA), ethylene glycol dimethacrylate (EGDMA), azobisisobutyronitrile (AIBN), FA and dimethylsulfoxide (DMSO) were used as functional monomer, cross-linker, initiator, template molecule, and po ...Более
